Patterns of immune evasion in triple-negative breast cancer and new potential therapeutic targets: a review.

Triple-negative breast cancer (TNBC) is an aggressive subtype of breast cancer characterized by the absence of progesterone and estrogen receptors and low (or absent) HER2 expression. TNBC accounts for 15-20% of all breast cancers. It is associated with younger age, a higher mutational burden, and an increased risk of recurrence and mortality.

Brain Freeze: Pembrolizumab-Induced Autoimmune Encephalitis in Triple-Negative Breast Cancer.

This case report presents the first known instance of pembrolizumab-induced autoimmune encephalitis in a 41-year-old female patient with stage IIIc triple-negative breast cancer. The patient developed expressive aphasia three days after starting pembrolizumab in combination with chemotherapy, prompting comprehensive evaluations that ruled out infectious or metastatic causes.

Parameter-efficient fine-tuning of large language models using semantic knowledge tuning.

Large Language Models (LLMs) are gaining significant popularity in recent years for specialized tasks using prompts due to their low computational cost. Standard methods like prefix tuning utilize special, modifiable tokens that lack semantic meaning and require extensive training for best performance, often falling short. In this context, we propose a novel method called Semantic Knowledge Tuning (SK-Tuning) for prompt and prefix tuning that employs meaningful words instead of random tokens.

Tramadol as a fentanyl adulterant: Prevalence and management in a ToxIC Fentalog study prospective cohort.

Background: Tramadol is an adulterant of illicit opioids. As it is a serotonin-norepinephrine reuptake inhibitor as well as a μ-opioid agonist, tramadol adulteration may worsen overdose signs and symptoms or affect the amount of naloxone patients receive.

Methods: This is a multicenter, prospective cohort of adult patients with suspected opioid overdoses who presented to one of eight United States emergency departments and were included in the Toxicology Investigators Consortium's Fentalog Study.

Setting: Pediatric sports medicine and orthopedics clinic.

Changes in Medication Complexity and Post-Hospitalization Outcomes in Older Adults Hospitalized for Heart Failure.

Introduction: Medication regimen complexity may be an important risk factor for adverse outcomes in older adults with heart failure. However, increasing complexity is often necessary when prescribing guideline-directed medical therapy at the time of a heart failure hospitalization. We sought to determine whether increased medication regimen complexity following a heart failure hospitalization was associated with worse post-hospitalization outcomes.

Can We Improve Geriatrics Recruitment? An Analysis of U.S. Geriatrics Fellowship Programs on X.

Geometric variations in nucleosomal DNA dictate higher-order chromatin structure and enhancer-promoter communication.

The dynamic organization of chromatin plays an essential role in the regulation of genetic activity, interconverting between open and compact forms at the global level. The mechanisms underlying these large-scale changes remain a topic of widespread interest. The simulations of nucleosome-decorated DNA reported herein reveal profound effects of the nucleosome itself on overall chromatin properties.

Pathology Findings and In-Life Correlates in the Nonclinical Development of Adeno-Associated Virus (AAV)-Based Retinal Gene Therapies.

Adeno-associated virus (AAV)-based vectors are the most frequently used platform for retinal gene therapy. Initially explored for the treatment of loss-of-function mutations underpinning many inherited retinal diseases, AAV-based ocular gene therapies are increasingly used to transduce endogenous cells to produce therapeutic proteins, thus producing site-specific biofactories. Relatively invasive ocular routes of administration (ROA) mean prominent procedure-related in-life, and histopathological findings may be observed with some regularity.
